Sylius Prometheus Metrics

Features

Observability

We use the artprima/prometheus-metrics-bundle (https://github.com/artprima/prometheus-metrics-bundle) bundle to collect metrics in the Prometheus format, which can then be used to build a dashboard with Grafana. These metrics are visible at the /metrics/prometheus URL of the website.

Default metrics are generated. It is possible to create custom metrics to track "Business" data, such as the number of created orders or the order amount.

Installation

Run $ composer require acseo/sylius-prometheus-metrics-plugin.
Add these few lines to the config/state_machine/sylius_payment.yaml

winzou_state_machine:
   sylius_payment:
      callbacks:
         after:
            sylius_order_items_complete_collector:
               on: 'complete'
               do: ['@metrics.order_collector', 'incrementPrometheusCounters']
               args: ["object.getOrder()"]

Installation without Symfony Flex

Run $ composer require acseo/sylius-prometheus-metrics-plugin.
